# Autorollers
|
|
|
|
Several of our dependencies are automatically rolled (updated) by bots.

|
## Clang
|
|
|
|
We use an auto-roller for Clang <https://autoroll.skia.org/r/clang-flutter>.
|
|
|
|
These rollers may fail if Clang catches a new compilation warning or error that it previously did not, or if a test relies on undefined behavior that has now changed in the new revision of Clang. It is best to resolve such issues ASAP to let the rollers continue and avoid a pile up of issues to resolve.
|
|
|
|
The rollers work by updating a [CIPD](https://chrome-infra-packages.appspot.com/p/fuchsia/third_party/clang/) package version in the [DEPS](../../DEPS) file. You can map from a CIPD version to a git revision by checking in CIPD.
|
|
|
|
## Fuchsia SDK
|
|
|
|
We use an auto-roller for the Fuchsia SDK on [Linux](https://autoroll.skia.org/r/fuchsia-linux-sdk-flutter)
|
|
These rollers may fail if the Fuchsia SDK contains a breaking change. It is best to resolve such issues ASAP to let the rollers continue and avoid a pile up of issues to resolve.
|
|
|
|
The rollers work by updating a [CIPD](https://chrome-infra-packages.appspot.com/p/fuchsia/sdk/core) package version in the DEPS file. You can map from a CIPD version to a JIRI snapshot or a git revision by checking in CIPD.
|
|
|
|
## Skia
|
|
|
|
We use an auto-roller for Skia rolls. It's status can be viewed at <https://skia-flutter-roll.skia.org/>. In case of build failures or other errors, ping the Flutter-Skia chat channel. In case you get no response, you can log in with an `@google.com` account and pause the roller (or ask someone with an `@google.com` account to do so). Please specify a descriptive reason and file a bug to re-enable the rollers as soon as possible.
|
|
|
|
The bot updates the `skia_revision` line of [`DEPS`](../../DEPS).
|
|
|
|
## Dart
|
|
|
|
The Dart SDK is automatically rolled by <https://autoroll.skia.org/r/dart-sdk-flutter>.
|
|
|
|
If there are any issues with this process or the autoroller dashboard, contact bkonyi@ or a member of the Dart VM team.

|
|
## Flutter Pub Roller
|
|
|
|
The bot account [flutter-pub-roller-bot](https://github.com/flutter-pub-roller-bot) runs the script at
|
|
[`packages_autoroller`](../../dev/conductor/bin/packages_autoroller) on post-submit of
|
|
every framework commit to keep the pub dependencies in the [framework](https://github.com/flutter/flutter)
|
|
up to date.
